Accel and Decel (733BDC)

Accel - The Accel trimpot is adjustable from 0-10 second of maximum output speed setting. The setting
of the accel time is approximately proportional to the rotation of the Accel trimpot. As an example, a
50% setting of the Accel trimpot will result in approximately a 5 second linear accel ramp from zero to
maximum speed. To test a setting, turn the speedpot to zero (fully CCW). Next turn the Accel trimpot
CW to the estimated accel setting. Quickly rotate the speedpot full CW and time the motor accel ramp
from zero to maximum speed. If necessary, adjust the Accel trimpot setting as needed and test again.
Decel - The Decel trimpot is adjustable from 0-10 second of maximum output speed setting. The
setting of the decel time is approximately proportional to the rotation of the Decel trimpot. As an
example, a 50% setting of the Decel trimpot will result in approximately a 5 second linear decel ramp
from maximum to zero speed. To test a setting, turn the speedpot to maximum (fully CW). Next turn
the Decel trimpot CW to the estimated decel setting. Quickly rotate the speedpot full CCW and time
the motor decel ramp from maximum to zero speed. If necessary, adjust the Decel trimpot setting as
needed and test again.
Note: Minumum, Maximum and Gain trimpot settings must already be completed to properly set and
test Accel and Decel. Refer to the Open Loop and Closed Loop Trimpot sections above for Minimum
Speed (MIN), Maximum speed (MAX), Current Limit (CUR LIM) and Gain trimpot adjustments.
